Launch of IOWN Network Solution for 400Gbps High-Speed Inter-Data Center
Connections that Reduces Construction and Operation Costs by 50%, and power
consumption by 40%~ Integration of technology of NTT’s IOWN and IP Infusion, a leading software company in theUnited States ~The IOWN Network Solution (400G) (hereinafter, The Solution) combines the IOWN-related
technologies of NTT Corporation (NTT) and those of IP Infusion Inc. (IP Infusion) (*1), a leadingsoftware company in the United States, to realize high-speed, high-capacity, and low-power
consumption communication.
NTT and ACCESS Co., Ltd. (ACCESS) (*2) have been strengthening the collaboration of the R&D andproductization of network OS as well as sales and support in the global market through a capital andbusiness alliance (*3) to develop the IOWN.
Today, nine companies, NTT, NTT Advanced Technology Corporation (NTT-AT), ACCESS, IP Infusion,
Broadcom Inc. (Broadcom), Edgecore Networks Corporation (Edgecore), UﬁSpace Co., Ltd. (UﬁSpace),
Fujitsu Optical Components Ltd. (FOC), and NEC Corporation (NEC), are announcing that they are
ready to provide the solution to realize 400Gbps high-speed data center connectivity by their close
collaboration, with their technologies and products. This solution will be sold by NTT-AT and IPInfusion.
With this solution, customers such as data center operators and telecommunication carriers canconstruct simple and lower cost inter-data center networks based on 400G ZR/ZR+ for high-speed
and long-distance transmission. This will contribute to a 50% reduction in the construction andoperation costs of the network equipment (*4), 40% reduction in power consumption (*4), and rackspace.

1. Background
The rapid increase in power consumption has become a social issue as the data amount in data
centers increases due to the development and spread usage of generative AI and machine learning.
As the data amount is expected to further increase in the future, there are growing expectations for
low-cost construction of high-speed connections between data centers to distribute expanding data
calculation processing and low-power consumption.
In constructing high-speed data center connections, software-hardware integrated network devices
with a limited number of optical transceivers options are usually used in the current network, which
poses a problem in terms of investment eﬃciency. In response, there is a need to improve investmenteﬃciency through the software and hardware disaggregation and the ﬂexible selection of opticaltransceivers.

2. IOWN Network Solution (400G) Overview
This solution provides a switch/router capable of long-distance transmission at 400Gbps. Its
software and hardware are disaggregated, it’s consisted of a network OS (software), a white box
switches/routers (hardware), and a 400G ZR/ZR+ optical transceivers (optical transceiver). Dependingon the needs, customers can combine optical transceivers that comply with the open standard andis fully validated.
Figure 1. IOWN Network Solution (400G) Overview

Features of IOWN Network Solution (400G)

① FOC and NEC optical transceivers are equipped with NTT Innovative Devices Corporation's
Photonics-Electronics Convergence devices that achieve low-power and stable transmission
performance and comply with the open standard speciﬁcations.
② A switch/router is realized by combining Network OS and white box switch/router, andcustomers can select the appropriate combination from the multiple white box
switches/routers and optical transceivers to meet the needs. (Fig. 2)③ By combining the transponder functions in switches/routers, it reduces procurement andmaintenance cost, power consumption, rack space usage, and construction lead time (Fig.
3).
④ Network OS that combines technologies of NTT and ACCESS/IP Infusion that provides a rich
set of functions that contribute to advance maintenance and operation quality improvementof customer networks.

5. Future Developments
NTT, NTT-AT, ACCESS, IP Infusion, Broadcom, Edgecore, UﬁSpace, FOC, and NEC will keep

collaborating with their technologies and products to meet the needs for high-speed and largecapacity connections between data centers, high-speed and large-capacity back-end networks in datacenters, and reduction of power consumption.
In addition, we will meet the needs for the advancement of the data center related networks, suchas the realization of high-capacity, low-delay, and low-power communication between data centersand various sites by connecting to IOWN APN.

6. Endorsement<Network OS Contributors>
Takehiko Kawazoe, Senior Executive Vice President, NTT"The presence of various global partners is essential to the promotion of IOWN. We are pleased thata new IOWN solution combining the technologies of NTT's IOWN and each company will be oﬀered
to the world. The NTT Group will continue to work with global partners to release IOWN products assoon as possible and contribute to advance the customer networks. By implementing IOWN, which
is a next-generation communication platform with high capacity, low latency, and low-power
consumption, we will contribute to realize a well-being society."
Tadashi Ito, President, NTT-AT“As a member of the NTT Group, NTT-AT is working on the distribution of IOWN technologies. We
expect that the launch of IOWN network solutions will accelerate the spread of IOWN technologies.
We will provide total systems/solutions that combine the network OS "Beluganos", which NTT has
developed together with IP Infusion, the optical transceivers and white box device, and will actively
contribute to the realization of the software-based and open architecture that NTT has been leading.
Although Beluganos has been primarily deployed in data center networks so far, we will expand it
into new business areas such as carrier and enterprise networks, and even as an IOWN solution fromnow on, aiming to develop our business as a system and service provider of IOWN solutions together
with domestic and overseas partners.”
